The two groups started off with a warm-up match of copying comical photos of animals with their faces, then faced off in a test of thigh strengths, with MONSTA X's Shownu and BTOB's Hyunsik displaying their enormous muscle strengths! To further "warm up" for the "real game", the two groups engaged in a game similar to handball, with BTOB easily defeating MONSTA X. 

Finally, for their "real game", the groups had to dress up in silly, comical costumes, and create their own choreography to a given song. You'll be able to see MONSTA X and BTOB all dolled up in skirts, pretty wigs, and more on 'MONSTA X-Ray', plus you'll want to find out which group had to face the punishment of going out on the streets dressed up in their costumes to promote the show to the public, right?
